(57) An outlet guide vane structure 6 for a gas turbine engine comprises outlet guide vanes 18 supported between inner and outer outlet guide walls 20, 22. The guide walls 20, 22 form a diffuser 24 aft of the guide vanes 18. The outer guide wall 22 is secured directly to a compressor casing 10. A support structure 26, 28, for example for supporting turbine nozzle guide vanes 38, is connected to an outer case 12 of the engine at a flange 48. The support structure includes struts 52 which pass through the outlet guide vane structure 6 to provide a load path 64 by which loads on the support structure are transferred to the outer case independent of the outlet guide vane structure 6.
